Mayon lava wall may collapse – Phivolcs

LEGAZPI CITY, Albay: The Philippine Institute of Volcanology and Seismology (Phivolcs) has reiterated its warning against entering the 6-kilometer radius permanent danger zone (PDZ) as lava wall collapse may occur that could lead to pyroclastic flow in the southeast quadrant of the restive Mount Mayon here.

“Possible collapse of lava wall might occur due to brittleness of the wall instigated by molten materials. Wall collapse is very dangerous because that could trigger pyroclastic flow,” Phivolcs regional director Ed Laguerta said on Monday.
